Reuse LA: Adapting Existing Buildings for the City’s Future

Adaptive Reuse in Practice: Zoning, Building Codes, and Case Studies
As California cities expand their adaptive reuse programs, architects must navigate a shifting patchwork of building codes, zoning ordinances, and evolving interpretations. This workshop explores the practical realities of adaptive reuse in Los Angeles, with a focus on early project phases: owner due diligence, programming, and schematic design.

Led by Roberto Vazquez, AIA, the session will examine how architects can help building owners design within “by-right” entitlements, avoid costly code triggers, and translate regulatory constraints into design opportunities. Drawing from multiple case studies completed over the last 18 months, the presentation will show how project teams can leverage zoning tools and alternative code pathways to unlock feasibility and avoid common pitfalls.

This workshop is designed for industry professionals seeking to deepen their understanding of adaptive reuse. Mechanical, structural, and fire protection engineers will also share insights on performance requirements, envelope compliance, and upgrade thresholds.

Whether you’re leading your first adaptive reuse project or refining your process, this session offers actionable tools and strategies grounded in real-world experience.

The program includes a 45-minute presentation followed by an interactive 45-minute Q&A. While the session may not answer every question, it aims to establish a foundation for continued discussion through a series of topic-specific salon sessions hosted by AIA|LA’s Building Performance and Regulations (BP&R) Committee, which meets virtually every Monday from 4:00 to 5:00 p.m.

SPEAKER

Roberto Vazquez, AIA
Sector Leader – Housing + Mixed Use, HED Architects

Roberto Vazquez is a leading voice in adaptive reuse policy and design in California, with over 20 years of experience and a career dedicated to revitalizing existing buildings. His portfolio includes a wide range of conversions, historic conservation, and major rehabilitation projects throughout Downtown Los Angeles and Southern California—from small-scale office conversions of just six residential units to large-scale adaptive reuse projects exceeding 1,000 units, including multiple high-rise developments.

Roberto has advised cities including Los Angeles, Santa Monica, Pasadena, San Jose, and the County of Los Angeles on adaptive reuse ordinances and implementation strategies. He contributed to the drafting of California’s statewide adaptive reuse bill (AB 3068) and participates in ongoing code reform efforts such as AB 529, which aims to expand adaptive reuse through alternative building code standards.

Before joining HED Architects, Roberto held leadership roles at AXIS and Omgivning, helping position both firms as key players in California’s adaptive reuse movement. He continues to champion sustainable, code-savvy design solutions that transform underutilized structures into vibrant, community-serving spaces.

His thought leadership has been featured in NPR, KCRW, Axios, Brookings, and the AIA|LA Advocacy Report. He currently serves as Vice-Chair of the AIA|LA Building Performance & Regulations Committee and is a frequent speaker at ULI, SEAOSC, VICA, Bisnow, and AIA|LA events.

LEARNING OBJECTIVES

AIA CES: Submitted for approval

1. Review how updates to Los Angeles’ zoning code encourage adaptive reuse and identify which codes apply across the city. 
2. Gain insight into lesser-known zoning tools, including Zoning Administrator Interpretations that support adaptive reuse. 
3. Understand how to apply the California Existing Building Code, including how the City of Los Angeles modifies it through the LA Existing Building Code. 
4. Learn how to apply the California Historical Building Code in adaptive reuse projects. 
5. Explore a process-driven approach to evaluating buildings for reuse, including early-phase design and entitlement strategies. 
6. Gain insights into structural and mechanical considerations critical to adaptive reuse, including Title 24 compliance and seismic upgrade triggers.
